Your experience is EXACTLY the same as mine, including the onset of symptoms and present symptoms. I picked up Ascaris roundworm in Qatar and was very sick on the plane home (and for a few more days) and then felt better for about a month. I would suggest that you try a parasite cleanse (not sure which is best) and/or Albendazole/Mebendazole and search through your stool for worms. Since you're in Canada, Cahill would be expensive for testing. Parawellness Research is just as good (IMO), and doesn't require travel. Best of luck!
